IPC: G06F3/02
Filed: 1990-01-30
Abstract: PURPOSE:To waterproof a keyboard through a simple working process of fixing a soft cover by engaging a projection of the soft cover with a recessed groove formed in a casing body to hold and fix the soft cover between a hard dressing cover and the casing body. CONSTITUTION:A stepped section 12 having locking holes 14 is formed around the key-operating window 9 of a casing body 1, and then a recessed groove 13 is formed in the inner peripheral part of the stepped section except the front side of the window. A member further formed is a soft cover 15 shaped to fit the shape of keys 10 of a keyboard assembly body 11 and having a projection to be fitted in the recessed groove 13 and a drainage groove 17. The projection on the rear side of the soft cover 15 is engaged with the groove 13, and the locking claws 20 of a hard dressing cover 19 are fitted respectively in the locking holes 14 to hold and fix the soft cover between the hard cover and the casing body. A waterdrop, even if its dripping occurs during reading operation of a bar code or the like through a readout window, flows through the recessed groove 17 down to the front side of the window without arriving at the assembly body 11 by means of the cover 15. The soft cover can thus be fixed through a simple working process to waterproof the keyboard.

Title: Cathode-ray tube
Inventor: TSUMURA OSAMU
IPC: H01J29/88
Filed: 1984-02-06
Abstract: PURPOSE:To decrease local heating of a valve by forming corrugation in axial direction on the inner circumferential surface of the valve positioned at the lapped section of a metal-backed layer and an interior conductive membrane. CONSTITUTION:Grooves 12 are formed in valve circumferential direction in continuous wave shape. By coating an interior conductive membrane 3 and by vapor-depositting a metal-backed layer 4, the creeping distance in circumferential direction is longer at the section where the grooves 12 are formed, and the area of this section is larger as compared with conventional ones which have no groove 12. Therefore, getting fewer as an adherent quantity per unit of the metal-backed layer formation metal which is vacuum evaporated in this section, and forming the metal-backed layer 4 thinner than conventional ones, and the area resistance becomes larger. For this reason, making the magnetic field of the deflective york, and getting lower the induced current generated in this lapped section 10, the local heating of the glass valve 2 is suppressed.

IPC: B41J2/32
Filed: 1987-01-31
Abstract: PURPOSE:To realize a sharp transfer, by a method wherein an auxilialy electrode for preheating a ribbon is provided in the vicinity of a printing electrode. CONSTITUTION:A printing head 5 depresses a ribbon 4 against a medium to be printed 7 disposed on a platen 8. An auxilialy electrode 1 passes an auxilialy current to a return electrode 2 to an extent not enough to melt an ink of the ribbon 4. A printing electrode 6 is selectively and electrically conducted as necessary, whereby the printing head 5 prints characters etc.. Due to the conductive current the ink of the ribbon 4 is melted to be transferred to the medium 7. After the completion of a printing action for one line, the auxilialy current from the auxilialy electrode 1 is stopped, and the printing head 5 stops traveling and separates from the ribbon 4. While the printing head 5 presses the ribbon 4 against the medium 7, a pressure roller 3 presses the ribbon 4 against the return electrode 2. In this manner, the ribbon 4 is preheated by the auxilialy current from the auxilialy electrode 1 and kept at a fixed level of temperature, whereby the ink coated on the surface layer of the ribbon is made easy to melt and the transfer of the ink to the medium can be facilitated.

Title: Fuel pump
Inventor: MATSUMOTO TATSUYA
IPC: F02M37/20
Filed: 1998-02-02
Abstract: PROBLEM TO BE SOLVED: To provide a fuel pump to suppress the decrease of a fuel discharge amount and have high fuel suction capacity. SOLUTION: A pump flow passage 41 is formed in a C-shape between a casing body and a casing cover 22 along the outer periphery of an impeller. Fuel sucked in the pump flow passage 41 is pressurized through rotation of an impeller and discharged from the fuel pump to the engine side. A gas discharge port 42 is formed in such a manner that it extends through a casing cover 22 and intercommunicates a pump flow passage 41 and the interior of the fuel pump outside a fuel tank. A gas discharge port 42 is formed in the terminal end 54 of the pump flow passage 41, and the diameter (d) of the gas discharge port 42 is set to a value within a range of 0.2 mm<=d<=0.9 mm.  Since the length of a pressurization flow passage running from a fuel suction port 40 to a gas discharge port 42 is increased, a negative pressure at the fuel suction inlet 40 is increased, and fuel suction capacity is improved. Further, since an amount of fuel discharged from the gas discharge port 42 togetherwith vapor is decreased, the decrease of a fuel discharge amount is suppressed.

CONSTITUTION:A shock absorber 1 is set in its preset damping force by a setter part 32, for instance, to a position of medium M, when, for instance, an output code signal A causes a fault by a wire break or the like of a control circuit 16, because the signal A always obtains a signal of 1, the output code signals A and B, output by 1 turn of a rotary valve, are as shown in a table. And assuming one period for a change of code outputting the equal code of soft S and dead band F, repetition of the period is detected in an abnormal output decision part 37. When a change of the code (1 period) increases not less than a number of times N, abnormality is decided, and a motor 13 is stopped. Now when assumed N for 1, the abnormality is detected while the rotary valve makes one turn.
